I haven't seen any discussion of Rotis here yet. Here are my downtown favourites:
1) Ghandi's, at Bathurst and Queen. Indian style rotis to die for. Butter chicken Roti is the best. Not open weekends for some reason.
2) Bacchus, at Queen and Brock. They have a huge variety of fillings, some not exactly traditional. Chedder cheese is really good on a Roti!
3) Flava, Yonge and Wellesly. Very nice. Friendly service, nice atmosphere, actual tables to sit at. The coconut curry shrimp roti is sublime.
4) Vena Restaurant Queen Street (646 Queen Street West.)
